Privacy Perception when Using Smartphone Applications

Abstract: Our smartphone is full of applications and data that analytically organize, facilitate and describe our lives. We install applications for the most varied reasons, to inform us, to have fun and for work, but, unfortunately, we often install them without reading the terms and conditions of use. The result is that our privacy is increasingly at risk. Considering this scenario, in this paper, we analyze the user’s perception towards privacy while using smartphone applications. In particular, we formulate two different hypotheses: 1) the perception of privacy is influenced by the knowledge of the data used by the installed applications; 2) applications access to much more data than they need. The study is based on two questionnaires (within-subject experiments with 200 volunteers) and on the lists of installed apps (30 volunteers). Results show a widespread abuse of data related to location, personal contacts, camera, Wi-Fi network list, running apps list, and vibration. An in-depth analysis shows that some features are more relevant to certain groups of users (e.g., adults are mainly worried about contacts and Wi-Fi connection lists; iOS users are sensitive to smartphone vibration; female participants are worried about possible misuse of the smartphone camera).

Conversational Interfaces for a Smart Campus: A Case Study

Abstract: The spoken language is the most natural interface for a human being and, thanks to the scientific-technological advances made in recent decades, nowadays we have voice assistance devices to interact with a machine through the use of natural language. Vocal user interfaces (VUI) are now included in many technological devices, such as desktop and laptop computers, smartphones and tablets, navigators, and home speakers, being welcomed by the market. The use of voice assistants can also be interesting and strategic in educational contexts and in public environments. This paper presents a case study based on the design, development, and assessment of a prototype devoted to assist students' during their daily activities in a smart campus context.

An Online Education System to Produce and Distribute Video Lectures

Abstract: Nowadays, the term “student” embraces people with different needs and lifestyles (e.g., people with part-time or full-time jobs, people with some forms of disabilities, etc.) and, in the attempt to reach out to these students, many educational institutes are recording and releasing classroom lessons. In this paper, we share our experience building ONELab, a system designed to capture, record, edit and stream video lectures. ONELab was designed to provide flexibility to educational contents (i.e., no time and geographical constraints) and to improve the students’ learning process. Moreover, the system had to be scalable and cost-effective. The system has been used in the 2017-18 Academic Year to manage the 49 courses offered by the five-degree programs available at our Department. In numbers, it supported 1,251 students and produced 1,376 video lectures (for a total of 2,064 hours). The usage analysis showed that students want to adapt the learning process to their lifestyle and showed that students who used ONELab acquired more credits (+119%) and had better grades (+9.4%) than those who did not use the system.

Do Conversational Interfaces Kill Web Accessibility

Abstract: Conversational interfaces are making web accessibility studies obsolete. Long-time has passed since the introduction of graphical interfaces. They revolutionized the way people used the computer. The desktop metaphor popularized and made easy access to the software but did not consider the specific needs of people with some form of sight and/or motion impairments. Accessibility, at that time, was a minor issue. The web changed everything and empathized the need to include people. Researchers from around the world began working on accessibility, which is still an issue on the agenda of many scientific labs. Despite this, we observe that today, with the diffusion of conversational interfaces, there is less need to bother about colors, fonts, size and many other visual features. Indeed, people might access to web contents through voice interaction. No need to see the graphic interface or to use input devices requiring the use of hands. The voice is everything you need, and accessibility has never been easier. Conversational interfaces are about to revolutionize accessibility and in this provocative paper, we show benefits, problems, and open issues that happen when these interfaces meet accessibility requirements.

On the Usage of Smart Speakers During the Covid-19 Coronavirus Lockdown

Abstract: The COVID-19 pandemic has dramatically changed every aspect of our professional and private life. It forced us to stay at home and it gave unprecedented power to technology. In this paper we focus on the emerging technology of smart speakers (e.g., Amazon Echo Plus, Google Home, etc.) and, through a developed questionnaire, we investigate how people use these devices. In particular, we analyze whether the human behavior has been affected by availability of these smart speaker. Results showed that the usage of these devices did not increase during lockdown, but it highlighted the presence of some privacy issues that might represent a burden to the diffusion of this type of technology.

Untangling between fake-news and truth in social media to understand the Covid-19 Coronavirus

Abstract: "Covid-19 is a virus developed to rule the world" is just one of the many fake-news published on the Web. In this pandemic period, the Web is flooded with real news, allegedly true or blatantly false. To understand how fake news is affecting the Covid-19 perception, we selected 40 news (either true or fake) related to the origin, diffusion, treatment and effects of Covid-19 and we asked 293 volunteers to express their opinion on the truthfulness of the news. Then, we propose an Awareness index to compute knowledge degree of the volunteers. The results highlight a large ignorance on medical news, ignorance that goes beyond educational background. The study highlights the need for Health Institution to enter social media platforms in order to clearly explain what is true and what is false on Covid-19.

On improving the engagement between viewers and TV commercials through gamification

Abstract: TV advertisements are less and less watched as most viewers turn their attention to the smartphone during commercial breaks. Therefore, broadcasters are facing a novel challenge: how to improve the engagement between viewers and TV commercials. In this paper, we investigate whether gamification can be a winning strategy. Indeed, despite some strategies that have recently been proposed (e.g., cross-media, use of specific mobile software), an effective approach to improve the engagement between viewers and TV commercials is yet to be found. We designed a game that involves the commercial break and the smartphone: during each TV advertisement, a simple question (e.g., “What was the color of the car?”) appears on-screen and the answer must be given through a special smartphone app. A player earns points if she answers exactly, otherwise she loses points. Results obtained from two different experimental assessment (within-subjects and between-subjects) revealed that a well-designed gamification strategy improves the marketing memorability (i.e., a measure of engagement) from 44% (no game elements) to 75% (with game elements). Therefore, gamification might be exploited by broadcasters and advertisers to improve the engagement between viewers and TV commercials.

Can IoT Wearable Devices Feed Frugal Innovation

Abstract: Recently, there has been a lot of talk about Frugal services, that is, services that use existing technologies for a purpose other than the one for which they were designed. In this paper, we study whether the IoT wearable environment can be a fertile ground for the production of Frugal services. Through a real-world study, we investigate whether these devices are widespread, if there are obstacles that limit their diffusion, if the sensors they are equipped with are deemed reliable and, finally, if people who own them have an altruistic propensity or not. The results, from the frugal point of view, are encouraging: the IoT wearable environment seems to be pervasive enough and ubiquitous, without great obstacles for their adoption. The provided sensors seem to be generally reliable, whereas the altruistic propensity might be questioned: in general, people are not inclined to share, but if the goal is clear (in our case we hypothesized a fight against Covid-19), altruistic propensity grows a lot.
